Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00024 | $0.00452 |
| Opus 5.5 | $0.00010 | $0.00181 |
| Sonnet 5.5 | $0.00005 | $0.00090 |
| Haiku 4.5 | $0.00002 | $0.00045 |
Grade A, and why
tuturuuu-development-tooling scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Tuturuuu Development Tooling
Keep workflow changes tied to the requested task or an observed recurring failure. Put detailed operational knowledge in the narrowest skill reference or existing docs page. Keep root AGENTS.md for cross-cutting constraints, not a growing incident diary.
For skill changes, make descriptions concise and discriminating. Keep the entrypoint focused on decisions and route substantial conditional detail to references. Preserve security, ownership, active runtime policy, and delivery boundaries. Remove generic encouragement, duplicate recipes, arbitrary approval pauses, and unsupported tool requirements. Do not turn a model-specific preference into a universal policy.
Audit canonical sources and symlink targets once. Managed plugin caches and runtime
system skills are installer-owned; update their source package when appropriate.
Preserve metadata, licenses, invocation policy, scripts, and useful references.
An audit may leave a file unchanged when it already has the right scope.
For prompt/skill maintenance, use references/agent-guidance-review.md for
placement decisions and realistic routing checks.
- For scripts and CI behavior, consult the relevant section of
references/ci-tooling-patterns.md. - For shared-checkout ownership, use
$tuturuuu-agent-coordination. - For a changed operating workflow, update the relevant
apps/docspage. - For plugin edits, keep folder/frontmatter names aligned, retain
agents/openai.yaml, and updateapps/docs/build/development-tools/codex-plugin.mdx. Release Please owns version bumps.
Run python3 plugins/tuturuuu/scripts/validate_plugin.py for plugin edits, then
focused non-build tests for changed scripts/configuration. Do not run local
bun check, setup or builds; require applicable exact-commit CI checks/builds.
For recurring coordination failures, prefer the evidence-state checker and
the program orchestration reference over
another universal prompt rule. Validation should
check meaningful structure and behavior, not require longer descriptions or fixed prose.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tuturuuu-development-tooling is a skill published in the GitHub repository tutur3u/platform (55 stars, last pushed yesterday), licensed Apache-2.0. It adds 24 tokens to every session and 452 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
